Jobs in Botany Project

I'm currently auditing a class at the public high school on Botany. The current assignment is to find two government-funded, and two non-government-related, jobs in Botany in Michigan. How exactly would I go about finding these?

I've tried some search engines, but they didn't seem to have anything on which are government-funded, and which are non-government-related.

To clarify, these jobs must require a college degree in Botany, and one of them must be federal, one must be state, and the other three must be non-government. And they must all be available in Michigan.

I would really appreciate some help, as I can find nothing useful by typical searches or "ask.com".
